Gossen Luna-pro
Digital Incident or Reflective Ambient Light Meter
The LUNA-PRO digital offers
many functions at an
inexpensive price. It is
user friendly, with just
three controls using only
five buttons. An especially
large and high contrast,
easy to read display, makes
full use of the meters
remarkable features.
The logic functionality is
truly remarkable, when the
measuring button is pressed,
in the (t) time mode and
held on, the meter switches
automatically into contrast
measurement. A series of
cursors on the analog scale
indicates the range of
contrast of the subject area
being measured. The cursor
that is flashing indicates
the current reading, until
the button is released.
This feature-packed meter is
energy efficient: about two
minutes after the last
reading was taken the meter
switches off automatically,
but retains in the memory
the last reading, and the
previously stored values of
shutter, film speed and
apertures selected. This
economic power management
requires the use of only one
1.5 V, AA Alkaline battery. |
